Diablo Canyon Power Plant seismic safety reports

Evaluates earthquake hazards at the DCPP on the central California coast.

Confirms the seismic studies and engineering evaluations provided sufficient safety margins against earthquakes.

Concludes Shoreline Fault did not pose a greater risk than the plant's existing seismic design basis.

Concludes that a credible maximum earthquake would not exceed the plant's seismic design basis.

Details earthquake focal mechanism data to identify regional fault orientations, slip styles and stress patterns.

Provides an analysis of the fault system and ensures the plant's seismic design long-term earthquake safety.

Documents fault zones near the plant and activities are in accordance with the California Energy Commission (CEC) recommendation.

Accounts for uncertainties in fault behavior, earthquake recurrence, ground motions and estimates seismic hazard for the site.

- Coming soon

Integrates all recent geological, seismological and probabilistic analyses.

Presents the updated three-dimensional representation of the subsurface geological structure.

Quantifies local site conditions to determine how these conditions amplify seismic ground motions.

Ensures that DCPP's infrastructure maintains adequate safety margins.
